ELEVATOR.

' SPECIFICATION forming part of Letters Patent No. 293,088, dated February 5, 1884, Applicalion for filed November 6. 1883. (No model.) i

i (bZl whom it may concern.-

* Be it known that I, AUGUST Kinoknnrnn, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Elevators; and I do hereby declare that the following isa full, clear, and exact description thereof.

My invention relates to balance-elevators for buildings, and will be fully described hereinafter. i

In the drawings, Figure 1 is a vertical section of my improved elevator. Figs. 2, 3, 4, and 6 show details of the same; and Fig. is apartly-broken side elevation of said elevator. Ais the car, which, by means of the usual wire cables, a, passing over the sheaves b I), properly mounted above top of well-room B, is connect .3 ed to the counter balancing bucket O. This bucket 0 runs the. whole height of thc'building between the posts 6 0, either close to the elevator-well, or at any distance fromit, as may be desirable, and it is guided along said posts c 0 by means of the notched bearings 0', formed in its flanged top 0 and bottom 0. Said bucket 0 is attached, in any desirable manner, to the wire cables at, and it is weighted, so as to counterbalance the-weight of the empty car A or of the platform used in place ofsaid car.

In its bottom f of said bucket is formed an opening, g, and just above said openingis fitted the valve D, of any suitable form, to one of the bearing-trunnions h of which is keyed on the weighted lever-arm h to keep said valve closed. The weighted end of said arm 71/ is provided with a hook, h whereon is attached the end of the valveoperating wire cable a. This wire cable a runs over pulleys b b above well-room =13, and thence, passing through the car-roof, reaches down to attach in the hook.

of atreadle,aflproperlymounted nearthefloor of said car A. A rubber strip, 0 is fitted around the flanged top and bottom of said bucket O, by means of which and of the coneshaped pipes E, provided in the path of said bucket 0, through the top and bottom stories of the building, a cushion of compressed air is obtained above-or below said bucket G, which willsafely arrest the same when, from some accident or other, a sudden rise or fall of said bucket is inevitable. This stopping device is designed to act in connection with a similar one provided 011 the car A itself. Rubber of a clutch-brake, L,

strips (1 d are fastened around the top and bot fed to the hopper E by a bucket-belt elevator, F, from the boot G. On the shaft of the beltwheel is mounted the pulley g, which is connected by proper belting with the driving machinery The hopper E is provided in its bottom opening with the valve D, similarto the valve D of bucket C, and saidvalve D is controlled by the wire cable a which, as the wire a may be run over pulleys or be cut to connect to both ends of a lever, H, fulcrumedon top of standard H in the attic, said wire a runs down thence, passing through the car, to the bottom of the well-room B, where it is attached to a hook, a", in the floor.

Alongthe post J, on one or each side of the well-room, I fasten a flat iron bar, K, which projects enough in the well to come in the path carried underneath the car or platform. Said clutch-brake L consists of the crank-shaft m, journaled in brackethanger M, bolted onto the underside of crossbar M of the car-bottom. Said crank-shaft is provided with a right-andleft screw-thread From the above description the operationof 10o my improved balance-elevator is readily understood. The hopper E being kept supplied with the proper quantity of lead shot by means of the elevating-bucket belt F, driven by the engine, the valve D in the bottom of said hop- I per is opened by the conductor through wire cable a until vthe proper amount of shot has run into the bucket G to raise the car A, which, by means of the hand-lever p, actuating the clutch-brake L against brake-bar K, can be stopped at either of the floors of the building. by the opening of the valve D of said bucket 0 through the wire cable a, connected to the treadle a,within reach of the conductors foot, the shot emptying from said bucket into the boot G of the elevating-belt F until the living weight of the car overbalances said bucket.

I am aware that heretofore the basement of the well-room has been constructed so as to secure an air-compressing chamber with the cushioned sides of the car-bottom; but I claim as new the fitting of a similar compressing chamber in the top story of said well-room, and providing elastic cushions along the sides of the car-top for that purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an elevator, acounterbalancing-bucket, 0, adapted to rise and fall in vertical ways, properly connected to the car or platform, and adapted to raise or lower the same respectively as the proper weight is emptied in said bucket from a valve-controlled hopper in the top of the'building or emptied from said bucket through a valve in its bottom, as set forth.

2. In an elevator, a well-room having the sides of its top story inclined inward toward the ceiling, wherein a sufficient volume of air may be compressed by means of elastic strips fitted on the corresponding sides of the cartop to gradually arrest the sudden rise of the ear, due to a breakage of some part of the hoisting mechanism or to some other accident, in combination with the similarly-inclined sides of the well room basement and the elastic strips fitted on the sides of the car-bottom, as set forth.

3. In an elevator, the counterbalancingbucket 0, having notched bearings c in its top I and bottom, and the automatic valve 1), in

combination with the bucket-belt elevator F, having the boot G and the valve-controlled The descent of the car is obtained hopper E, substantially as shown and described, and for the purpose set forth.

4. In an elevator, the bucket O, filled with shot 0, in combination with thewire cables a, the sheaves b b, and the car A, substantially as shown and described, and for the purpose set forth. 7

5. In an elevator, the clutch-brake L, consisting of right-and-left-threaded crank-shaft m of articulated levers N, having threaded sleeves n a, slotted fulcrum 0, and clutchingarms a n, both supported by bracket-hanger M and fulcrum-hin 'in bolt 1? on cross-bar M, in combination with flat iron bar K of post J, connecting rod or link an, and hand-lever p, substantially as shown and described, and

for the purpose set forth.

6. In an elevator, the inclined sides 13 of the well-room top story and the elastic strips (1 alongthe sides of car-top A, in combination with the inclined sides B of the well-room basement story, and the elastic strips (1 along the sides of the car-bottom A substantially as shown and described, and for the purpose set forth.

7. In an elevator, the inclined sides 13 of the well-room top story and the elastic strips cl on sides of car-top A, in combination with the wires a, sheaves b -b, the funnel-shaped pipes E, fitted in the' basement story on'the path of counterbalancing-bucket 0, having elastic strips 0* around its bottom, substantially as shown and described, and for the purpose set forth.

S. In an elevator, the funnel-shaped pipe E, fitted in the top story 011 the path of the counterbalancing-bucket G, having the elastic strip 0* around its top, in combination with the inclined sides B of well-room basement, and the elastic strips (1 on the sides of the carbottom, substantially as shown and described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of \Viscousin, in the presence of two witnesses.
